Extending Hyperlatex

As mentioned above, the documentclass command looks for files that
implement LaTeX classes in the directory ~/.hyperlatex and
the system-wide Hyperlatex directory. The same is true for the
\usepackage{package} commands in your document.

Some support has been implemented for a few of these LaTeX packages,
and their number is growing. We first list the currently available
packages, and then explain how you can use this mechanism to provide
support for packages that are not yet supported by Hyperlatex.
